EXERCISE DEVICE WITH POWER INPUT MEASURING CAPABILITY AND USER APPLIED RESISTANCE MECHANISM

摘要

An exercise device includes a stationary support structure and a power input arrangement supported by the support structure, which are configured such that the user applies input power to the exercise device at the power input arrangement. A rotary member is supported by the support structure, and a power sensing is driven into rotation by input power applied by the user. Input power applied by the user is transferred through the power sensing arrangement to impart rotation to the rotary member. The rotary member is in the form of a rotary resistance-providing member, which is rotatably supported on the support structure by the power sensing arrangement. In one form, the power sensing arrangement is driven into rotation via a chain drive system interposed between the power input arrangement and the rotary power sensing arrangement. The power input arrangement may be in the form of a pedal arrangement, and the rotary resistance-providing member may be in the form of a flywheel rotatably mounted to the stationary support structure via the power sensing arrangement. A user-operated resistance arrangement acts on the flywheel to resist rotation of the flywheel. The user-operated resistance arrangement may be in the form of a caliper arrangement that selectively engages the flywheel in response to user actuation. Representatively, the support structure may be in the form of a stationary bicycle frame that includes a user-supporting seat and a set of handlebars.
